I have worked at four fortune five hundred Companies in my career. I have seen many physicians in my time.The group included those at Mayo Clinic, Barrows Neurological Institute, University of Pittsburgh Alzheimer's Research Institute , etc. A select group I felt were very good. Dr. Siperstein I feel is VERY EXCELLENT! He had throughly reviewed my past medical records even those from Arizona. He was personable and focussed on my condition and what possible treatment plans might be possible. He asked good clarifying questions. I felt that he is very knowledgeable, does his homework completely, and presents the possible treatments with particular attention to newer less invasive approaches with regard to my age , my underlying medical conditions, and benefit risk assessment. I feel so fortunate to be referred to Dr. Siperstein. Having met him l give him my highest recommendation. As an aside, I saw several other physicians about my condition and they never came close to Dr. Siperstein in terms of their pre appointment preparation, my underlying conditions, and/or a clear risk/benefit assessment. You at Cleveland Clinic are so fortunate to have him heading up your Endocrinology Department .I sure you already knew that. Thank you Dr.Siperstein !
